Abstract
An explosion venting device for metallurgical furnace enclosures consists of a plurality of panels adapted for restrictive movement relative to the roof and sidewalls of the enclosure and cover openings therein. The panels absorb the shock blast of an explosion occurring within the housing by lifting outwardly from the housing walls. Being restrictively movably mounted, the blast force may be vented in any desired direction. When the explosive force ceases, the panels will return to their rest position against the housing.
Claims11
In a metallurgical furnace station enclosure wherein a housing is provided formed from frame members which support a series of panels, the housing enclosing the furnace during charging, melting, refining and tapping, the improvement wherein:
- a plurality of said panels are constructed as explosion venting panels adapted for restrictive movement relative to the frame members of the housing, said venting panels movable from a closed position during normal operation of the furnace to a restricted open position upon explosive forces being exerted from within the enclosure.
In a metallurgical furnace station enclosure wherein a housing is provided formed from frame members which support a series of panels, the housing enclosing the furnace during charging, melting, refining and tapping, the improvement wherein a plurality of said panels comprise explosion venting devices adapted for restrictive movement relative to the frame members of the housing, said venting devices comprising:
- a venting panel which maintains the integrity of the surface area and furnace enclosure when in a rest condition;
- at least two trunnions extending from the sides of said venting panel;
- and
- at least two brackets mounted on and extending out from the frame members of the housing, said brackets supporting said trunnions on an angled surface so that in the event of an explosive force being exerted from within the housing, said venting panel moves up and out away from the housing enclosure providing a vent through which explosive forces escape the enclosure and upon dissipation of the explosive force said vent panel returns to a closed rest position against the enclosure because of the angled surface of the bracket upon which the trunnions are slidably mounted.
